Green Porsche Cayenne S Hybrid Gets Federal Tax Credit

By dancurranjr On December 9th, 2010

When it comes to green cars, a few names jump right to mind like Toyota with its Prius and GM with the Volt. One name that most of us don’t associate with green cars is Porsche. I tend to think of Porsche as a performance brand, and it is. The company is famous for its fleet of exotic and high-end performance vehicles like the 911 and others.

Porsche also makes a SUV that is popular around the world called the Cayenne and the latest version of the Cayenne dubbed the S Hybrid has around for a while. The SUV may be a hybrid, but anything with the Porsche crest has to perform, and the Cayenne S does. The big SUV can hit 60mph in 6.1 seconds and has a top speed of 150 mph. The vehicle is rated for 20mpg in the city and 24 mpg on the highway by the EPA.

Those fuel efficiency figures might not sound that great when compared to other hybrids, but when you consider this is a performance vehicle it’s pretty impressive. The Cayenne S Hybrid has a combined power output of 380hp from a supercharged V6 combined with an electric motor. Porsche has announced that the Cayenne S Hybrid has qualified for a one-time federal tax credit of $1,800. The vehicle stickers for $67,700 before that credit is taken off the price. I’m not sure the sort of folks that can afford to spend nearly $70,000 on a SUV really need a tax credit.

Supercharged Porsche Hybrid

By dancurranjr On May 10th, 2009

porsche-cayenne-hybridThe Cayenne becomes the first Porsche to get a petrol/electric hybrid drivetrain. The SUV also has the world’s first hybrid using a supercharged internal combustion engine, currently used in the Audi S4 and A6 3.0 TFSI. The Cayenne Hybrid prototype previewed two years ago highlighted a normally-aspirated 3.6-litre V6.

The Cayenne S Hybrid’s 3.0-litre V6 develops 333hp – like in the Audis – and 440Nm. Together with the electric motors, the combined outputs come to 374hp and 550Nm giving the SUV a 0-100kph time of 6.8sec, fuel economy of some 11kpl and CO2 emissions of 210g/km. Porsche is promoting ‘output of an eight-cylinder with fuel consumption of a four-cylinder’.

The Lexus RX450h and Mercedes-Benz ML450 Hybrid first used this principle. The RX450h has a 299hp 3.5-litre V6 good for 7.9sec and 15kpl, while the ML450 Hybrid features a 340hp 3.5-litre V6 with 7.8sec and 9.4kpl credentials. The Cayenne S Hybrid’s optimum performance/economy balance is due to the ability of cruising with the combustion engine switched off at speeds up to 138kph.

The Cayenne S Hybrid will hit showrooms next year, although Thai sales have yet to be confirmed or will be limited if available. The ML450 Hybrid isn’t available in right-hand-drive yet, making the RX450h the only hybrid-powered luxury vehicle available in the Thai market so far at B6.33m. Expect the Cayenne S Hybrid to cost over B10m.

Economy of scale will improve when the all-new Panamera saloon goes hybrid within three year. Also due within this time frame are sister-models Volkswagen Touareg and Audi Q7. Not to be outdone by its competitors, BMW is preparing to join the hybrid race with the X5 and X6, whose prototypes have already been shown to the public at motor shows.

The Cayenne S Hybrid is not the first Porsche with an environmental conscience. Earlier this year, Porsche unveiled its first diesel-powered model: Cayenne Diesel whose 3.0-litre V6 engine was sourced from Audi. The 240hp unit is nearly as economical as Cayenne S Hybrid at 10.8kpl.

FYI: There’s a special 10% excise tax for hybrid-powered cars in Thailand. But those with engines over 3,000cc or 220hp are not eligible for the rate, so all the SUVs here must face the maximum levy of 50%.

Test Drive and Review: 2011 Porsche Cayenne S Hybrid

By dancurranjr On April 5th, 2009

porsche-cayenne-hybridTwo years ago, Porsche unveiled a concept of its first hybrid, a Cayenne V-6. It came with a single electric motor slotted between the engine and the automatic transmission. That went against the prevailing “power-split” hybrid wisdom practiced by Toyota and Ford, whereby a gasoline engine interacts with a pair of electric motors to form a continuously variable transmission. Porsche says two advantages of its system are that it enables the Cayenne to retain its towing capacity and conventional all-wheel-drive system.

We spent a day driving the production Cayenne that’s powered by the 333-hp, 3.0-liter supercharged V-6 in Audi’s S4 rather than the Volkswagen 3.6-liter V-6 in the concept. Mated to a 52-hp electric motor, it gives a maximum output of 374 horsepower, enough grunt for a claimed 0-to-60-mph time that’s just 0.4 second slower than the V-8–powered Cayenne S’s 6.0 seconds. An eight-speed automatic transmission takes the place of the six-speed unit in the concept. This powertrain will later find its way into the upcoming Panamera.

Like many hybrids, the Cayenne can be driven solely on electric power up to a speed of 30 mph for the most feather-footed drivers. To enable efficient regenerative braking to charge the 288-volt nickel-metal hydride battery, the torque converter locks up very early, but Porsche had to painstakingly tune the shifts to avoid jerkiness in this mode.

One of the key features of the Cayenne hybrid is its ability to coast at speed to eke out better gas mileage on the highway. At speeds up to 86 mph, the engine will shut down, only to be restarted when the driver asks for torque by stepping on the gas pedal. In order to do this smoothly, a clutch between the engine and the electric motor reengages as the engine fires, a process that Porsche says takes 0.3 second.

The company claims the vehicle averages 26 mpg in the latest European combined cycle—a 27-percent improvement over the nonhybrid Cayenne V-6—which is very impressive for a 5700-pound SUV. (That’s about 350 pounds heavier than the V-8 Cayenne S.)

We found that the hybrid system works very well. There’s just a slight whine to indicate that the Cayenne is operating in electric mode, and it moves seamlessly between gasoline and electric power. Under hard throttle, the vehicle gets along smartly, the torque from the electric motor impressively augmenting the smooth and sonorous V-6.

The electrohydraulic power steering is a touch light, but this is still a very sporty SUV. On the highway, it’s eerie when the engine goes quiet while coasting, but reengagement of the gasoline engine is amazingly smooth. Our only reservation was the occasional clunky downshift while braking from low speed, no doubt caused by the locked torque converter as energy is redirected into the battery. Porsche claims this is a prototype glitch.

The hybrid Cayenne S will cost significantly more than the standard $60,215 ­Cayenne S. We estimate a base price of about $70,000.

Porsche Cayenne Hybrid Offers V8 Performance With Speeds Of 86 MPH

By dancurranjr On March 28th, 2009

porsche-cayenne-hybridPorsche Cars North America, Inc has announced its new Cayenne S Hybrid electric car which offers buyers a high-performance solution. The vehicle can drive at highway speeds of up to 86 mph without using its combustion engine. The company will launch the new Hybrid car in 2010.

“When driving with just the combustion engine, the Hybrid Manager also will ensure the engine is operating as efficiently as possible in reference to its load. It switches the electric motor to an alternator mode, so the fuel consumed by the combustion engine not only efficiently powers the Cayenne but also generates electricity that can be ‘parked’ in the NiMH battery,” a Porsche spokesman said.

The Cayenne S is more likely to become the best energy efficient Hybrid car made by Porsche.

This isn’t like any standard electric car. This vehicle delivers V8 performance while maintaining a four-cylinder efficiency. It uses a full parallel hybrid design with a programmable motor acting as a cross between the main engine and the transmission.

“Using a parallel full hybrid design with the electric motor between the combustion engine and the transmission, Porsche engineers have been able to drive at speeds up to 86 mph without at all using the combustion engine,” the spokesperson said.

The Cayenne S Hybrid car is probably the best high-performance car to run at top speeds. Modern electric solutions are designed only for in-town travel or city traffic. However, this vehicle is built for the highway without using its engine which can reduce C02 emissions by 20 percent.

Porsche engineers designed the car to move 0-to-100 km/h in just 6.8 seconds. This is achievable by using a small percentage of its engine while slowly depending on the battery once it’s cruising. This design certainly must have other automakers, such as GM, Ford, and Chrysler, re-thinking high-performance while offering fuel efficiency.

“The Cayenne S Hybrid uses a supercharged Audi 3.0-liter V6 engine with Direct Fuel Injection (DFI), 333 horsepower and 324 lb-ft of torque from 2,900 to 5,300 rpm. It is mated with 52-horsepower three-phase synchronous electric motor that produces up to 221 lb-ft of torque and also acts as an alternator, and the combined power units are joined to an eight-speed automatic transmission,” the spokesperson said.

Hybrid Manager is a new technology which decides when to turn on and off the engine. For example, if the vehicle is coasting on the highway, it will turn off the engine while delivering more power from its batteries. This technology is known as parallel full hybrid and offers three classic modes.


Porsche Goes Hybrid

By dancurranjr On March 10th, 2009

porsche-cayenne-hybridPorsches are known for the sound of their rippling horsepower under the hood, but the company’s new gas-saving hybrid actually runs on batteries more than half the time – leaving the driver with little more than the sound of the wheels on the road.

Using a parallel full hybrid design developed with Volkswagen and Audi engineers, the prototype Cayenne S Hybrid relies on a combination of internal combustion and electric power to reduce C02 emissions and boost mileage from 14 mpg in the city to 24 mpg.

That’s still only half what the Toyota Prius hybrid gets, but then again, it’s an SUV. The company wants to improve mileage further by the time the Cayenne S Hybrid hits the market in 2010.

While many other hybrids deliver their benefits primarily in city traffic, the Cayenne S Hybrid allows drivers to cruise at up to 86 mph on the highway using electric power alone. If that’s a little slow for you, put the pedal down, the combustion engine comes alive again, and off you go.

That’s key for the designers of the new Cayenne. While it’s not the first hybrid – or even the first hybrid SUV – coming to the market, it’s the first Porsche hybrid and the company has been very careful to retain the performance that its customers expect.

Porsche touts it as delivering the “power of a V8 and the efficiency of a four-cylinder”.

“The Cayenne Hybrid is a special driving experience,” said Michael Leiters, project manager of the Cayenne product line, after a recent test drive in and around Porsche’s hometown of Stuttgart.

“It can be completely electric or use the engine at the same time to improve acceleration – there is also what we call ‘sailing’, or coasting with the engine off at speeds up to 86 mph, when the driver can only hear the wind.”

It’s not an idle boast: On a recent test drive for reporters, one passenger remarked on the hum of the electric motor as the Cayenne whizzed down the road, but the noise turned out to be coming from the radio, which wasn’t properly turned in to a station. After it was shut off – silence.

So far, fuel consumption is not as good as the more conventional diesel version of the Cayenne, making its debut at this week’s Geneva Auto Show. But Porsche is working on the hybrid primarily for the US market, where diesels are not as popular, said Klaus-Gerhard Wolpert, director of the Cayenne Product Line for Porsche.
